Product details
Overview
1N4106-1 from Microsemi is a 500 mW, 12.0 V ±5% metallurgically bonded glass Zener diode in DO-35 package, rated for junction temperatures from –65 °C to +175 °C and qualified to JANTXV level per MIL-PRF-19500/435. It delivers stable voltage regulation with 200 Ω dynamic impedance at 250 mA test current and 9.2 mA maximum Zener current, used in precision reference and power supply feedback circuits.
For engineers reviewing the 1N4106-1 datasheet, 1N4106-1 pinout, 1N4106-1 application, or 1N4106-1 equivalent, key selection criteria include its 12.0 V nominal Zener voltage, 200 Ω Zener impedance at IZT, 0.05 µA reverse leakage at 9.2 V, ±0.080 %/°C temperature coefficient, and DO-35 axial-leaded hermetic packaging for high-reliability military and aerospace systems.
Technical Context
The 1N4106-1 operates as a two-terminal voltage reference device biased in reverse breakdown, with Zener regulation occurring at 12.0 V under 250 mA test current (IZT). Its metallurgical bond construction ensures low noise density (≤1 µV/√Hz below 6.8 V) and radiation hardness per Microsemi MicroNote 050.
Thermal performance is defined by RθJL = 250 °C/W (junction-to-lead, 10 mm lead length) and linear power derating from 500 mW at 25 °C to zero at 175 °C. Polarity is marked by cathode band; regulation requires cathode positive relative to anode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V ±5%, 1 W rating, DO-41 package, 200 Ω ZZT, +0.075 %/°C TC | Higher power but larger footprint; not MIL-qualified | Select when commercial-grade 1 W dissipation is required and JANTXV qualification is unnecessary |
| MMBZ5242B | 12 V ±5%, 350 mW SMT, SOT-23 package, 250 Ω ZZT, +0.085 %/°C TC | Surface-mount only; no hermetic seal or radiation hardening | Select for space-constrained PCBs where MIL-spec and hermeticity are not mandated |
Compared with 1N4106-1, 1N4742A offers higher power margin but lacks military qualification and hermetic packaging, while MMBZ5242B enables miniaturization at the cost of environmental robustness and radiation tolerance-making 1N4106-1 uniquely suited for high-reliability, thermally extreme, or radiation-exposed deployments.

FAQ
What is the nominal Zener voltage and tolerance of the 1N4106-1?
The 1N4106-1 has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5% at 250 mA test current (IZT). This value is measured under thermal equilibrium at 25 °C ambient and reflects the voltage at which the device enters stable reverse breakdown regulation. The 1N4106-1 datasheet specifies this as the defining electrical parameter for selection in reference design.
Is the 1N4106-1 suitable for high-reliability military applications?
Yes, the 1N4106-1 is qualified to JANTXV level per MIL-PRF-19500/435, confirming full compliance with military screening, testing, and traceability requirements. Its metallurgically bonded construction, hermetic DO-35 package, and operation from –65 °C to +175 °C make it appropriate for flight-critical avionics and space-qualified subsystems where failure is not an option. The 1N4106-1 meets these standards without derating.
What is the maximum reverse leakage current for the 1N4106-1, and at what voltage is it specified?
The 1N4106-1 exhibits a maximum reverse leakage current (IR) of 0.05 µA at a reverse voltage (VR) of 9.2 V. This specification appears in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet and directly impacts accuracy in high-impedance reference divider networks. Low IR ensures minimal error contribution from the 1N4106-1 itself in precision analog circuits.
Does the 1N4106-1 have radiation hardness, and is it documented?
Yes, the 1N4106-1 is inherently radiation hard as described in Microsemi MicroNote 050, a publicly available technical note. Its metallurgically bonded glass structure provides tolerance to total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and nuclear-hardened platforms. Radiation performance is an intrinsic property of the 1N4106-1 construction-not a test add-on-and is validated across the full family.
What is the thermal resistance and power derating behavior of the 1N4106-1?
The 1N4106-1 has a junction-to-lead thermal resistance (RθJL) of 250 °C/W at 10 mm lead length, and its rated average power dissipation is 500 mW at 25 °C. Power must be linearly derated to zero at 175 °C, beginning at 50 °C for lead temperature or 25 °C for ambient conditions on a typical FR4 board. This derating curve is shown in Figure 2 of the 1N4106-1 datasheet.
